Hi everyone. I'm trying to make my srt201 work with a zinc air cell 675 instead of the original 625px mercury batt that is now banned. It came with one but it died this morning ! Just at the beginning of a back packing trip in Rajasthan India. I found a zinc air battery that is one of the alternatives. But the needles still moves to the box when I choose BC instead of "on", which is is the battery check. Also the light metering seems weird compared to what I had before. I tried with a guy to take off the sticker in the cap and put carton paper around the batt to make it hold more or less in place (aaah India). But it seems it doesn't work. People recommend a #9 washer but here in Udaipur I couldn't find one.

Any tips or help would be greatly appreciated ! Thanks !
